-------------------------------------
[~alex.parvulescu], this is the issue we were talking about yesterday.
> SegmentNodeState.fastEquals() can trigger two I/O operations
> ------------------------------------------------------------
>
> Key: OAK-4558
> URL: https://issues.apache.org/jira/browse/OAK-4558
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Reporter: Francesco Mari
> Assignee: Francesco Mari
> Fix For: Segment Tar 0.0.6
>
>
> The implementation of {{SegmentNodeState.fastEquals()}} compares the stable
> IDs of two instances of {{SegmentNodeState}}. In some cases, reading the
> stable ID would trigger a read of an additional record, the block record
> containing the serialized version of the segment ID.
> This issue is about evaluating the performance implications of this strategy
> and, in particular, if it would be better to store the serialized stable ID
> in the node record itself.
